Motion of the Worlds,rces of mutual attraction. The problem of the motion of an Earth satellite can be regarded as a particular case of the “n-body problem,” about which one can draw information from the classics of celestial mechanics: they have plenty to say on this subject!

Methodological Approaches and Problems,orce acting on a particle with the same mass as the body and placed at the same distance from the center of the Earth as the center of mass of the body. This obvious, but easy to forget fact can have surprising consequences!

One can picture how such a spaceship, moving along an unwinding spiral trajectory around the Earth, attains escape velocity and, free to move in
